Before the September 11, 2001 attacks, an airline’s stock was trading at around $36 per share. Immediately after the attacks, the share price dropped by $14.40. Let U(t) be this cost at time t, and take t = 11 to represent September 11, 2001 . What does the given information tell you about lim t→11 U(t) ? lim t→11 U(t) = $36.00 lim t→11 U(t) = $14.40 lim t→11 U(t) = $25.20 lim t→11 U(t) does not exist

The graph shows a rough representation of the (aggregate) market depth of the stocks comprising the S&P 500 on the day of the U.S. stock market crash at 2:45 pm on May 6, 2010 (the "Flash Crash"; t is the time of the day in hours, and m(t) is the market depth in millions of shares). (a) Compute the following. (If a limit does not exist, enter DNE, and say why.) lim t→14.75- m(t) = The limit does exist. The limit does not exist because it diverges. The limit does not exist because the limit from the left does not match the limit from the right. lim t→14.75+ m(t) = The limit does exist. The limit does not exist because it diverges. The limit does not exist because the limit from the left does not match the limit from the right. lim t→14.75 m(t) = The limit does exist. The limit does not exist because it diverges. The limit does not exist because the limit from the left does not match the limit from the right. m(14.75) = (b) What do the answers to part (a) tell you about the market depth? Just prior to 2:45 pm, the $&P market depth was approaching million shares, but then fell suddenly to million shares at 2:45 exactly, then immediately following 2:45 it began to recover at values close to million shares.

For this problem, use the coffee cooling equation given below, where C represents the temperature of the coffee in degrees Fahrenheit, and t is time in minutes. dC dt = −0.4C + 28 (a) How long will take a cup of hot coffee that is initially 180 degrees to cool down to 100 degrees? (Hint: You can solve the ODE for the particular solution C(t) ) (b) Does this rate of change equation also make sense for predicting the future temperature for a glass of iced tea? Why or why not? (Hint: try plotting a slope field for this differential equation. What happens if the initial temperature is cool?)

A Ferris wheel is built such that the height h (in feet) above ground of a seat on the wheel at time t (in seconds) can be modeled by h(t) = 53 + 50sin⁡(π10t − π2). a. Find the period of the model. What does the period tell you about the ride? b. Find the amplitude and the range of the model. What can we say about the ride? c. Find and interpret the average rate of change of h(t) on the time interval [2, 2.5].
